Polygons - Pentagons Polygons: Properties of Pentagons. To find the sum of the interior angles of a pentagon, divide it up into triangles... There are three triangles... Because the sum of the angles of each triangle is 180 degrees... So, the sum of the interior angles of a pentagon is 540 degrees.

What Is a Polygon With Five Sides? If a pentagon consists of equal sides and equal angles, it is referred to as a regular pentagon; otherwise, it is called an irregular pentagon. A pentagon consists of five straight, connected sides. If one of the five sides of a given shape is a curved line or if the five-sided shape is not a closed figure, then it is not a pentagon.

How many faces, edges, and vertices does a rectangular pyramid have? A rectangular pyramid has 5 vertices, 5 faces, and 8 edges. A rectangular pyramid has a rectangle for a base and triangle faces. Since the rectangle has four sides, there are four triangular faces. An edge is a line segment that connects any two sides. Each side of the rectangle connects to a triangle (4 edges), and there are connections between the trangles (4 edges). 4 + 4 = 8 edges.

How many faces, edges and vertices does a hexagonal pyramid have? How are they determined? The base of the pyramid is a hexagon, a figure with 6 edges and 6 vertices. Because it's a pyramid, we have an edge extending up from each base vertex, and all of these edges converge at a single additional vertex for a total of 12 edges and 7 vertices.

How Many Lines of Symmetry Does a Pentagon Have? A line of symmetry is a line in a two-dimensional shape where the remnants on both sides are exact mirrored versions of each other. A line of symmetry in a regular pentagon must go from the center of any side to the vertex directly opposite to it. Because a regular pentagon has five sides, it also has five lines of symmetry. Most regular polygons have a number of lines of symmetry that are equal to the number of its sides. Related Questions.

How many faces, sides, and vertices does this dodecahedron have? Best Answer: A dodecahedron has twelve faces, twenty vertices, and thirty sides. Strictly speaking, that diagram is not a dodecahedron because it is two-dimensional. It is the net of a dodecahedron. When folded up it will have 12 faces, 20 vertices and 30 edges. Note that these figures must fit the formula F + V = E + 2 which applies to all polyhedra. 10 faces, 38 sides and 25 vertices. In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα 'twelve' + εδρον 'base', 'seat' or 'face') is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid.

- Triangles have 3 sides, squares have 4, pentagons have 5 and octagons have 8. A figure or shape is not considered a polygon if it has rounded sides or if its sides intersects at any place other than at the ends of each side.

- The n stands for the number of sides the polygon has. So, a pentagon has exterior angles that measure 360 / 5 = 72 degrees. The second angle is called the interior angle, which is the supplementary angle to the exterior angle.

How Many Sides Does a Regular Polygon Have? Quick Answer. The number of sides a regular polygon has is indicated by the name of the polygon. For example, a pentagon has five sides, and an octagon has eight sides. The fewest number of sides a polygon can have is three, but there is no upper limit.

- Answer by GB. A regular pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon.

- The hexagon had 6 vertices with 3 diagonals which gives you 18 divided by 2 equals 9 diagonals. I tested the others and this method worked. I also noticed a pattern between the number of sides and how many diagonals came from each vertex. The pentagon had 2, hexagon 3, heptagon 4, and if the pattern continues the octagon has 5. With further thought and conversation with other colleagues I developed a formula that can. be used at all times.
